Visual motions in large region, retinal periphery, and in far depth elicit the inevitable perception of self motion (vection) in the opposite direction to those visual motions. We investigated whether voluntary attention affects the perceived vection direction. The opponent-directional motions were presented on a CAVE-type display where the size, the eccentricity, and the depth were identical in opponent motions. The subject was instructed to pay attention to one direction of visual motion and to judge the perceived vection direction. Vection was perceived in the direction opposite to the non-attended motion, indicating the non-attended motion dominates vection. Next, attentional effect on the uni-directional motion was compared with that on the opponent motions. In the uni-directional-motion condition, the vection was perceived in the opposite direction to the attended motion or the whole motion. This is consistent with the previous findings without attention manipulation. The present study suggested that the attentional modulation of the vection occurs when the opponent-directional motions were applied or the visual motion has unstable components.
